Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon RX 5500
IntroThe Radeon HD 7870 XT has a clock frequency of 925 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is made up of 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.
Compare all of that to the Radeon RX 5500, which makes use of a 7 nm design. AMD has set the core frequency at 1670 MHz. The GDDR6 memory works at a frequency of 14000 MHz on this card. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 5500 should in theory be a small bit better than the Radeon HD 7870 XT overall. (explain)
Texel RateThe Radeon RX 5500 will be quite a bit (about 65%) faster with regards to texture filtering than the Radeon HD 7870 XT. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon RX 5500 is superior to the Radeon HD 7870 XT, by far. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
